Fiat Idea outside temperature sensor fault

Interesting problem. I had a similar issue with my old Saab 9-3. The symptoms were slightly different, but it also involved the climate control acting up and throwing weird temperature readings. I'm no expert, but did you check the sensor itself? Could it be faulty?

Thanks for the input! I haven't directly tested the sensor yet. I was hoping to avoid replacing it if it's just a wiring problem. When you had the problem with your Saab, did it eventually point to a faulty sensor or something else? I'd rather not throw parts at it without a better idea of what's wrong.

Well, after messing around with it for a while, I eventually gave up and took it to a workshop. They diagnosed it as a corroded connector causing intermittent signal loss. It might be worth getting a professional opinion. Saved me a ton of headaches, even though it stung the wallet a bit.

Thanks, I appreciate the advice! I'll probably do the same and take it to a workshop. They mentioned a repair cost of around 95€, so I'm guessing they'll check for a defective cable or plug connection.
